Hi Evan, Great to hear things are looking good for you and that the block discard performance is there. If possible, keep running the kernel from -proposed for a bit longer, just to make sure nothing comes up on longer runs.
I spent some time today performing verification on all the kernels in -proposed, testing block discard performance [1], and also running through the regression testcase from LP #1907262 [2]. [1] https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1896578 [2] https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1907262 All kernels performed as expected, with block discard on 4x 1.9TB NVMe disks on an i3.8xlarge AWS instance taking 3-4 seconds, and the consistency checks performed returned clean disks, with no filesystem or data corruption. I have documented my tests in my verification messages: Hirsute: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1896578/comments/26 Groovy: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1896578/comments/27 Focal: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1896578/comments/28 Bionic: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1896578/comments/29 I have marked the launchpad bug as verified for all releases. I'm still running my own testing, with my /home directory being on a Raid10 array on a Google Cloud instance, and it has no issues. If things keep going well, we should see a release to -updates around the 21st of June, give or take a few days if any CVEs turn up.
